C9A5B Baja build

[C9A5B]

So I run my baja a while back and wasn't running so good, and then wouldn't start at all after 10mins of driving. I rebuilt the carb with the rebuilt kit because it wasn't starting and the carb seemed to be leaking fuel. After the rebuild it was still leaking but seemed to be coming out of the intake. I put a new 29cc headkit in because maybe there wasn't enough compression on the 23cc. Try starting yesterday and still nothing. All the bolts are tight, new gaskets. Its confusing the sh*t out of me lol. Rebuilt carb, new headkit, new spark plugs. Pulled the plug out and has fuel on the plug. The high and low needles are at factory settings. Do I need a new carb? Can the fuel tank be a problem? Please help.

Have tried a new plug? Are the pulse holes lined up?

I would just buy a brand new carb before you go tearing shït apart again

And while your at it replace all fuel lines and fuel filter inside the gas tank it’s a few bucks more but well worth it, trust me! ??

And +1like Doug said get a brand new plug!!! This one gets everyone ?

I think we need a Help, my engine wont start thread. With all the places people should start. Do we have one? Can a mod make it a sticky? Or I can start one

Yeah tried new NGK plugs, are the pulse holes the little holes on the carb?

That's a great idea?? why don't you start one??

Yes the little holes in tha gaskets manifold and carb?? if they don't line up it will not run???

Yeah thats what I was thinking, I've got a new fuel tank and carb in the basket.

Yeah they are lined up, should fuel be coming out of the intake like where the filter is connected?

Did you check to see of you're even getting spark? All the new spark plugs in the world wont fix that if you're not even getting spark to begin with.

 

[crucialRC]

Try a genuine Walbro carb and like @TheRipper said, check for spark.

Yeah getting spark

Yeah I'm looking at getting the wt 990

 

[cbaker65]

Yeah getting spark

Yeah I'm looking at getting the wt 990

What kind of carb insulator do you have?

Composite type will warp an cause leakage ,we had all talked about this a while ago!...

 

[crucialRC]

Might wanna try the 1107??

This is the one I got, any good?

What's the difference?

 

[crucialRC]

1107 is a bit more user friendly with the choke.

If it is aluminum an as long as its been milled good ,then you should be good on that!....

But if you have the composite like this one ,it would not be good!

Expanding on what @crucialRC said, basically the same, but has a choke and slightly larger venturi. Which should pock up for any marginal air loss caused by having a choke
